Rendering Problems - Tough One

dholt wrote on 7/10/2004, 12:56 PM
When I try to render my video as a mpg-2 using DVD architect NTSC video stream or DVD NTSC it starts to render then I get a error message from Vegas which says The reason for the error could not be determined.

When I render the video to an AVI file then to an mpg-2, same result?
When I try to rendor the AVI directly to DVD architect I get interlace artifacts during movement? The whole video is lower field first.

Normally I don't have problems and have produced many videos but this is a new one. Is Vegas taking a dump on me or is it some weird type of thing I'm not catching? Thanks for your help

Just a couple of things I'd try (just a guess). I'd check to see that you're using standard framerates/sizes and run it through something like VirtualDub to see if there are any weird anomalies.

Can you render a portion of it or does it immediately crap out? Maybe there's one problematic section you can remove.

Hey, worth a shot....

Look at your system, and check the heat. This is a VERY common problem, system overheat killing an MPEG render. In the past, we used to have to run fans on the outside of the box to keep it cool.
Search the forums, you'll find a lot of heat-related failures during MPEG renders.

The new problem I'm having now is that when I render to an MPG-2 I get to 6% then the approximate time left hits 00:00 but the elasped time keeps going but I can't get past the 6% completed.

This also happens when I render the video to an avi uncompressed and then to an MPG- 2?

I appreciate the support on this since it's making a music video project hell right now in the rendering stages.

So, you can render an uncompressed, but not the MPEG 2 from the uncompressed?
Have you tried EndItAll to kill all background apps during the render process? Have you checked for heat issues? disconnected system from the internet/cable modem during render?

Spot,
I really appreciate your support and help on this.

How do I do an enditall. Heat could be an issue since I live in Phoenix,AZ but I done lots of videos without ever having this problem. I tried rendering in a cool room first thing this morning with two fans on the computer right after start up, same problems. I'll also try disconnecting my modem but I was not on the internet while rendering.

This ones really got me preplexed. I done lots of videos and done tons of special effect work and then suddenly this????

Power down; open up your case and take a can of compressed air and blow the dust off the motherboard the CPU fan and heatsink.

I periodically open up my machines and do a "dust patrol."

If the problem is your CPU heat sink and/or fan can'tr move air because of dust, then lowering the room temp is unlikely to help much.

Actually your latest symptoms sound like your AVI source file might be corrupt in some fashion. Have you tried rendering just around the 6% area, or just rending after the 6%?

Dholt, Scott's absolutely right...dust bunnies and CPU's don't get along. Here in Utah, I have to keep air conditioning low in the editing room for this single reason, and keep the CPU, intakes, and exhausts clear. And still I occasionally get crashes on long projects. Just had a 6 hour project turf it last night mid render.
Also, as Scott suggested, try rendering to the 4:2:2 codec as a new track in the trouble spot. Could be you've got weirdness.
You running build 160? Look to HELP>About Vegas to check.
